Specifically, I'd like a series of mouths with different expressions in a digital image file. I want to be able to take a mouth, and chroma-key out the background so that I could apply them Robot Chicken-style to minifigs. I'd be using them in Final Cut to animate the mouths of minifigs in stop motion animation. Preferably I'd like them to be in the style of the recent minifig designs; that is to say very expressive and fitting in with the current style.

Again, I am just looking for the mouths. I'd like to have expressions, in addition to various levels of open to animate speech. My skills are lacking, and I'd like to have a step up from than drawing a black oval and pasting it over the mouth, or digitally manipulating a shape in post production.

It would look something like this, but with a style closer to the minifig mouths being released now. Any help would be greatly appreciated. I really want to try this idea out, but lack the design skills to make them myself.

Does anyone have or know where to find an extensive library of brick (not minifig) decal templates? Specifically, I am looking to decal two 2x4 tiles, two 1x8 tiles, and the side of two 2x4 bricks. I just picked up the Shuttle Adventure, but I want to make it more authentic-looking with some NASA decals. . .

UPDATE:Found some templates that I could work with to create the appropriate decals. Now I've printed out a couple of proof sheets, but it appears that I can't get my printer to print with high enough resolution to bring out all of the detail on my decals. Mostly what I'm missing are the stars on the NASA logo (used the "Color Insignia" on this page) and the stars on the smaller U.S. flags for the side panels. Would anyone be willing to help me out by printing these out on waterslide decal paper and shipping them to me at cost? I'd really appreciate an assist. Thanks!
